Earlier in the week my fridge/freezer was buzzing, not really bad so i didn’t pay no mind to it anymore, woke up about 2hours ago and i thought there was a tank in the kitchen. . . I emptied it and found the cause, it was a build up of ice around the fan housing which the fan kept catching on its revolutions. . . . I sorted it out and it made me smile, i had a jig to ‘ one step beyond ‘ playing on the radio as well. . . :P
